The Rackhams Advertising Sign Board is designed for business owners, taxi operators, and delivery services who need a mobile, high-visibility branding solution that does not require permanent vehicle modifications. Its primary benefit is its versatile, weather-resistant double-sided display that attaches securely to smooth surfaces using vacuum-suction technology, ensuring your message is visible to both traffic and pedestrians. While it offers excellent portability and ease of customization, potential users should note that the board is only compatible with perfectly smooth, non-porous surfaces like glass or clean metal, and it must be removed before entering automated car washes.

The board is designed for standard city and suburban driving. We recommend removing it before high-speed highway travel to reduce wind drag and ensure maximum safety.
The vacuum-mounted suction cups are designed specifically to avoid the scratching associated with magnets or clamping brackets, provided the surface is kept clean.
The board is compatible with standard sign-making vinyl and adhesive-backed printed panels. Ensure the board is clean and dry before applying decals.
No, the suction mechanism requires a smooth, non-porous surface to maintain a vacuum seal. It will not work on textured or heavily curved surfaces.
Yes, provided the glass is flat or gently curved and free from aftermarket window tint film, as the suction can damage the film.
Simply release the locking lever on each suction cup. If it remains stuck, gently lift the edge of the rubber seal with your finger to break the vacuum.
Clean both the roof surface and the rubber suction cups with glass cleaner or isopropyl alcohol to remove dust and wax.
Ensure the surface is completely flat and not obstructed by roof ridges or molding; reposition the board to a clearer area.
Wash the rubber in warm, soapy water to remove debris and oils, which will help restore flexibility and seal integrity.
Setup is straightforward: clean the mounting area, place the board in your desired position, and engage the suction levers. Compatibility is limited to vehicles with flat or gently curved roofs composed of glass, aluminum, or smooth-finished steel. Avoid mounting on sunroofs or glass with tint films, as the suction can potentially damage or bubble the film. For maintenance, clean the suction cups with mild soapy water and let them air dry to restore their "tackiness." Periodically inspect the rubber seals for cracks or debris, and store the board indoors during prolonged periods of non-use to extend the lifespan of the mounting components.
